THEODORE Hv CURTIS. OF LOUISVILLE. KENTUCKY.

CAR-TRUCK.

Specification of Letters Patent.

Patented April 7, 1908 Application'filed June 10, 1907. Serial No.378,325.

To all whom it may concern:

Be it known that I, THEODORE H. Opens, a citizei'i of thellnited States,and a resident of the city of Louisville, in the county of Jefl'ersonand State of Kentucky, have invented certain new and useful Improvementsin CarTrucks, of which the following is a full, clear, and exactdescription.

My invention relates to cartrucks, and especially to cast integral orbuilt-up sidetruck-bolster, and has for its principal objects'thefollowing: the integral side-frame with provision for inserting theintegral truck-bolster and bolster-guides, the rigidly securing of theside-frames together by the spring-beam which hold the side-frames inproper alinement, the remov- .able oil-cellars to permit theremoval ofthe car-wheels and axles from the side-frames without removing any partexcept the oilcellars, the construction of a car-truck embodying theintegral side-frames and integral truck-bolster, thereby eliminating theuse of bolts excepting those securing the oil-cellars, and also theproviding of means for keeping the side-frames substantially inalinement and rigidly held together and still of quick removal of'thecar-wheels and axles or the truck-bolster which is accomplished by meanshereinafter described and particularly pointed out in the claims.

In the accompanying drawings, formin a part of this specification andwherein like symbols refer to like parts wherever they occur, Figure Iis a full side view of the cartruck showing a small section at thecorner of the truck bolster. Fig. II, is a sectional view through centerof the car-truck, and Fig. III is a full end View of the car-truck. Fig.IV is a sectional view through the center of the truck-bolster andside-frame showing spring-beam with the bolster springs and spring seatremoved. Fig. V is a sectional view through the center of thetruck-bolster and spring-beam showing the respective clearance of samThe side-frame, 1, with the bolster-opening, 11, therein, is made withthe journalbox-saddles, 2, cast integral with the sideframe and the oilcellars, 3, attached by the bolts, 4. Said bolts being adjustable andthe tightening of the adjustclose the journal-box-saddles togetherv toexclude the dust from entering the joints between the journalbox-saddlesand the oil-cellars and also preable bolts will permitting l ventingvibration or rattling of the oil-cellars. l The adjustable bolts arelocated to tighten l or draw across the said joints in such a mannerthat the tightening of said adjustable bolts will cause thejournal-box-saddles and oil-cellars to close together andform asecuredust proof non-vibrating joint. The adjustable bolts are preferably madethreads for adjustment, but any other substantial holding may be used inlieu of the bolts. If desired theoil-cellars can be attached to theside-frames when same extend over the journal-box-saddles, 2. Thejournal-box saddles, preferably formed with the well known Master CarBuilders standard dimensions and to receive the Master Car Builderscontained parts, such as the journal bearing and the journal-bearin -keyand axle dust guard; are he d rigidly together by the sprin -beam, 6,with rivets, 17, securing the sprmg-beam to the extended Thetruck-bolster, 10, is made with bolster guides, 9, and spring-seats, 19.The width and height of the truckbolster is less than the width andheight of the opening, 11, in the side-frames, thereby permitting theinsertion of the truck-bolster in the opening, 11, and the truck-bolsteris then raised and engages the bolster-guides, 9, with the top orcompression bar of the side-frames, 1.

When the bolster-springs, 8, are applied under the spring-seat, 19, andresting on the lower spring seats, 7, the truckbolster will beheld inposition and secured to resist end thrusts by the bolster-guides, 9,transmitting the thrust to the bolster-guide bearings on the sides ofthe compression-bar of the sideframe, 1, and to resist side thrusts bythe sides of the truck-bolster transmitting the thrust to the verticalsides of opening, 11, in the side-frame. The truck-bolster can beremoved at any time by raising same until the frame seats, 18, strikethe bottom of the compression bars of the side-frames, which willrelieveall weight on the bolster-sprin s and permit their removal. When the b0ster-springs are removed the truck-bolster can be lowered until thebolster-guides, 9,

frames and the truck-bolster can be taken out of the side-frames endwise. The lower ,s ring-seats, 7, rest upon the extended anges, 16,, ofthe side-frames, also upon the spring-beam, 6. The car-wheels. 13, are

with screw 2, and the oil-cellars, 3, are

also t e jo'urna -box-lid., The side-frames,'1,

disengage the compresslon-bars of the sideflanges, 16, of theside-frames.

mounted on axles, 14. The journals, 15, revolve under the journal-boxsaddles, 2.

Obviously the construction of the car-f. truckadmits of modificationswithin the .scope of my invention, and therefore, I do not wish to belimited to the specific construction ofmy invention: For example,although a cast metal side frame is shown in the drawing the inventionis equally applicable to a built-upj side-frame -when the journal-boX-saddles, are plermanently se-' to the side-frame, or t etruck bolster can e made of the built-up design and be .over said -boster-o enings bein with bolster-guide earmgs an des to bolster'havin -'ulistand'ing bolster cooperate wit said bolster-guide,- earings, thelatterand said bolster-guides constituting the means for preventingendwise shiftin ofthe truck bolster, and journal-boxsa dles at ends ofeach side-frame and-removable oil-cellars attached to journalbox-saddlesby bolts, said bolts being adjustable and so. located that thetightening.

of the adjlustable bolts will close the'journalbox-sadd es andoil-cellarsv together to exclude the dust from 'enterin the joints between the journal-'box-sadd es and oil-cellars,tsubstantially asdescribed. l

2. In 'a railway ear-truck, the combinar .tion 'ofthe side framehavinbolster-openin s therein-to receive the en 's of the truck- 4 bolster,that ortion of the saidside-frames, over said b0 ster-openings beingprovided with bolster-guide bearings and a truck-bolster havingupstanding bolster guides to cooperate with said bolster-guide bearings,

the latter and said bolster-guides constituting-the-means for preventingendwise shifting of the-truck-bolster," and journal-boxsaddles' at endsof each side-frame and removable oil-cellars attached to saidsideframes. bybolts, said bolts being adjustable andso located th'atthetightening of the adjustable bolts will close the journal-boxsaddles andoil-cellars together to exclude the dust from entering the jointsbetween the j0ur'nalb0x-saddles and oil-cellars, substantially asdescribed, i f

In testimony whereof I affix my. signature in the presence'of twosubscribing witnesses:
